swung0x48 aba329cc53 [Docs] (Disaggregated): P6's plan and contract draft; the working notes move from a local directory into the repository

Two things land together: the plan and contract draft P6 needs before it starts, and the
working notes that until now existed on exactly one machine.

1. P6's plan and contract draft (neither started; not one line of code)

docs/Disaggregated/P6-SPAWN-PLAN.md the package plan
docs/Disaggregated/P6-CONTRACT-DRAFT.md the contract draft (moves to
MG_Remote/CONTRACT-P6.md when c6 lands)

The three findings that mattered, all written into the documents:

a. P6 is SMALLER than its roadmap cell suggests. The transport primitives are already in
the tree and already tested: SocketDoorbell including hangup detection and the two
lost-wakeup fences (Doorbell.cpp:211-360, four cases in FdPassingTest), SCM_RIGHTS fd
passing, ShmSegment::Adopt, and the SurfaceOp / WindowKind schema already defined in
protocol.fbs. inproc uses a real second shm mapping rather than an alias, and
SessionRings.h:22-28 says that was done so today is not the first time it runs. P6 is
assembly plus a control plane plus a process, not "write a socket transport".

b. The evidence for "P6 is only a transport swap" has EXPIRED. It was bought by P5c, whose
audit found 59 direct memory accesses in a tree that already looked clean. P5e changed
the tree again. So the first package, a6, is a read-only audit that writes no code, and
every contract row that depends on it is marked PENDING a6 rather than decided in
advance.

c. P6 does not get a game running on the phone. ANativeWindow* is meaningless in the child,
and protocol.fbs:186-196's own comment says Android transfers the window out of band -
that band is P12. P6 lands pbuffer / surfaceless / offscreen, which is what HeadlessGL,
the split-equivalent lane and trace replay need, and which is exactly what P6's own exit
gate measures. A real window reaching the server is a named refusal. This gets its own
section because "P6 is done" would otherwise read as "the game runs now".

The contract adds rule G: a role may not name a process-local handle. It extends P5c's
rule E (a role may not name the other role's memory) from memory to identity - EGLDisplay /
EGLSurface / EGLContext / ANativeWindow* / fd number / pid / mapped address either cross as
a token this contract defines or they do not cross, and a descriptor crosses only through
SCM_RIGHTS, where the kernel renumbers it.

What P5e left for P6 gets its own section. The latch semantics are already designed
(ARCHITECTURE.md:504) and are copied unchanged. What is new is that after run-ahead the
client no longer waits while the peer process can DIE: the client holds records that were
published and will never be applied, and Android's freezer suspends the child without
closing anything. So slow and dead must be distinguishable WITHOUT a timeout threshold.
That is P6's only new design; everything else is carriage. It shares a predicate with E1's
outstanding re-specification (ID-122), and the two should be designed together.

Two gates carried over from P5e's lessons: G2 requires integration-spawn's test-name set to
match integration-split's name for name, because a differing set means the lane is quietly
running less; and the arm-proof gate requires every entry to record the child pid and
transport=spawn in its OWN private log - ID-124 established that this kind of false green
really happens, and a spawn lane that actually ran monolith would pass every other gate.
S2's shape must be settled before it is written, and the document says why: E1 is the
cautionary case.

2. The working notes move into the repository (docs/Disaggregated/notes/, 415 .md files)

ROADMAP / CURRENT_STAGE_PROGRESS / MEASUREMENTS cite ruling numbers, audit line numbers and
the provenance of gate figures from ~/w7/notes/, a directory that exists on one machine and
is under no version control. A record cited hundreds of times that lives only locally is not
a record, so it moves in whole, with its directory structure intact.

Only .md moves. Scripts, run logs, census and gate result JSON, patches, APKs and nm dumps
stay where they are: they are evidence DATA rather than documents - large, regenerated per
run, and mostly carrying absolute paths and device serials that mean something only on the
machine that produced them. The mapping and this split are written in
docs/Disaggregated/notes/README.md.

Two exceptions are recorded there too: P6's BRIEF has been promoted to a first-class
document and keeps no copy under notes/, so the two cannot drift apart; and recovered/ holds
material salvaged from failed workflow runs, which may duplicate the like-named phase
directories and is kept because a few of those were the only complete version at the time.

CI's citation lint takes docs/Disaggregated/*.md only (non-recursive), and notes/ is
deliberately outside it: those notes' file:line citations were written against their own
code heads, and resolving them against today's HEAD would fail wholesale - which is not an
error, it is their correct state as a historical record. To check one, use the revision it
declares (--rev).

3. Inconsistencies fixed in passing

- README.md's status line still said P5e was in progress while the stage table already said
closed.
- CURRENT_STAGE_PROGRESS's next-step item 1 still listed the exit gate as pending, though
(a) and (b) were run in the previous commit; rewritten to closed plus the one item that
actually remains (E1).
- ROADMAP's P6 row still had the pre-phase plan in three of its cells; it now carries the
package order, the scope boundary and the two new gates.

Checked with check_doc_citations.py: 125 citations across docs/Disaggregated/*.md, 0 problems.

Paths under MobileGL/. DirectGLES.cpp / Managers.* = MG_Backend/DirectGLES/. Kinds: live = dereference of the frontend ProgramObject; id = GetLifetimeId() + client-allocator probe; mint = MGPipeSlots().Acquire; rec = record-only arm. "hit" = runs on every draw, memo hit included.

1.5 Off the steady path, still apply-thread

GetBackendProgramId :6151-6178: ValidateProgramName :6152 + GetProgramObject :6157 (sticky BARRIER_PULLED, FieldOwnership.def:149,155), scope :6166, Find/GetOrCreate :6168-6170, SyncToBackend :6174. ShaderStorageBlockBinding :10020-10042: the same two forwards :10022-10023, scope :10029, Find :10031, GetLinkVersion() :10038.

2. What records and applier state ALREADY carry

MGPipeApplierState::DrawProgram / DispatchProgram / BoundShaderCso + ProgramBindingSerial (MG_Pipe/PipeApply.h:691-695), written by MGPipeApplyBindShaderState (PipeApply.cpp:2919), ...SetDrawProgram (:2980), ...SetDispatchProgram (:2995), cleared by ...DeleteShaderState (:2941) and MGPipeApplierReset. Catalogue: MG_Pipe/PipeCalls.def:162-164,180-181.
MGPipeShaderCsoRecord (PipeApply.h:370-380): Gen/Live, MGPProgramDesc Desc (MG_Pipe/MGPipeTypes.h:585-597 - Cso, StageMask, GlobalUboSize, ReservedNumSamplesOffset, SpirvStatus, NativeFloat64, PointSizeDemoted, EnableSpirvValidation, MGPBlobRef Spirv[6], MGPBlobRef Reflection), GlobalConstants
- GlobalConstantsVersion + GlobalConstantsSerial, Serial. Two tables, ordinary and composite band (PipeApply.h:503,511). Serial moves on every applied create_shader_state including a re-issue on the same handle - that is how a RELINK travels - and a re-issue clears the block and bumps GlobalConstantsSerial (PipeApply.cpp:2895-2914).
Emitters: MG_Impl/Pipe/ProgramEmit.h EmitShaderState :105-159, AcquireShaderCso :212-292, EmitGlobalConstants :169-209; driven from MG_Impl/Pipe/PipeFill.cpp:3162 (NewShader/NewShaderBindings) and :3188 (NewGlobalConstants). The shutters (MG_Impl/Pipe/Tracker.h:364-371 plain, :419-448 pipeline) ALREADY mix GetBackendStateVersion, GetBlockBindingVersion, GetImageUnitVersion, GetUniformWriteSetVersion and the identity into bit NewShaderBindings.
A server-owned clean key that exists and is never read: m_syncedShaderCsoSerial (Managers.h:2415,2517), stamped from the record at Managers.cpp:12944-12966. Nothing in the tree calls GetSyncedShaderCsoSerial() at this head - P4a's D-B3 landed the producer without the consumer. P5e is its first caller.
Death: object_death covers ShaderCso by handle (Managers.cpp:328-345); delete_shader_state is emitted at PipeFill.cpp:1807-1827.
Handle-keyed twin machinery already on this registry (Managers.cpp:10757 TwinRegistry<ProgramObject, BackendProgramObjectImpl, MGPipeKind::ShaderCso>): FindByHandle (Managers.h:429), GetOrCreateByHandle (:453), ReleaseByHandle (:505), NoteStateForHandle/StateForHandle (:473-484).

3. The gap

G-A. The archive is not server-owned. MGPipeApplyCreateShaderState stores the DESCRIPTOR and deliberately not the artefacts (PipeApply.cpp:2915-2918); all seven MGPBlobRefs are Size 0 and LinkArtifacts/SpirvArtifacts ride beside the record as companion pointers (ProgramEmit.h:230-260). So every read in 1.2's SyncToBackend row is a read of ProgramObject::m_artifacts/m_spirv, which Link() REPLACES in place (ProgramObject.h:1104, ProgramObject.cpp:348-356,518-522). Fix: fill the refs - the client encodes once per link with the existing codec (MG_State/GLState/ProgramState/ProgramArtifactsCodec.h; the verify build already pins the round trip at PipeApply.cpp:1171-1202) into SEG_STAGE, the applier decodes into record-owned LinkArtifacts/SpirvArtifacts. No new fields - Desc.Reflection and Desc.Spirv[6] simply stop declaring 0.

G-B. Three POST-LINK mutable reflection fields have no wire form. They live inside LinkArtifacts, so an archive snapshot alone is wrong:

field	setter	counter	server reader
`uniformBlockBinding[i]`	`SetUniformBlockBinding` `ProgramObject.h:1017-1027`	`m_backendStateVersion`, `m_blockBindingVersion`	`:5463`
`uniformSamplerOrImageUnitIndex[loc]`	`SetUniformSamplerOrImageUnitIndex` `:830-850`	`m_backendStateVersion` (+`m_imageUnitVersion` for images)	`:4851`, `:5546`
`shaderStorageBlockBinding[name]`	`SetShaderStorageBlockBinding` `:1035-1048`	`m_blockBindingVersion` ONLY	`:4464`, `Managers.cpp:10811,10821`

Fix: one new record set_program_bindings, kCtxState, kVarTail|kHostSpan, head MGPProgramBindings { MGPipeHandle Cso; Uint64 Signature; Uint32 BlockBindingCount, SamplerUnitCount, StorageOverrideCount, Pad; } and three tails: Int32 BlockBindings[] (dense, GL uniform-block index order), {Uint32 Location, Int32 Unit}[] (sparse), and {MGHostSpan Name, Int32 Binding}[] for the storage overrides - a name span because the override map is name-keyed BY DESIGN (ProgramObject.h:1030-1034: three index spaces, one coordinate). Signature is computed CLIENT-side with the same commutative hash as Managers.cpp:10832-10841, so the rebuild clause is a Uint64 compare and the name tail is touched only on a rebuild. Record gains BlockBindings, SamplerUnits, StorageOverrides, Signature, BindingsSerial; a re-issued create clears all of them for GlobalConstants' reason (PipeApply.cpp:2903-2909). Dirty rule: bit NewShaderBindings already exists and its shutter already reads all three counters; the emitter is a fourth method on MGPipeProgramEmitterInstance(), latched on (Cso, backendStateVersion, blockBindingVersion), emitted BEFORE EmitShaderState (a rebuild inside the verb must already see the bindings).

G-C. MapUBO() has no run-ahead answer. :5380/:5382 runs when ResolveGlobalConstantsRecord declines (bit 12 off, sentinel, short block) and is a torn read of globalUboScratch. Under a live wire with run-ahead that arm is Fatal{UnmigratedVerb,"set_global_constants"}, not a fall-back.

G-D. Frontend-pointer keys. The stash (:4097-4098) and both memos (:5257, :5279) key on the object address; re-key on {slot,gen} + server serials. No record needed.

4. The retirement design

Twin key = the ShaderCso handle. SyncCurrentProgram takes an MGPipeHandle on the run-ahead arm; PrepareForDraw reads MGPipeApplier().DrawProgram, PrepareForCompute .DispatchProgram (PipeApply.h:691-693). Twin = GetOrCreateByHandle(h) (Managers.h:453). The Find/GetOrCreate(StatePtr) pairs at :4415-4416, :5337, :6168, :10031 and ResolveGlobalConstantsRecord's HandleOf :4242 go, and with them scopes :4236, :4329, :5328, :6166, :10029 - five of the twenty S7 must retire.
The record replaces the object in SyncToBackend, whose signature becomes (MGPipeHandle, const MGPipeShaderCsoRecord&): artefact reads answered from the record's owned archive (G-A), binding reads from its tails (G-B). GetLinkedShaderSnapshot :12049 is a debug log and is deleted on this arm; GetExternalIndex() in messages becomes the handle.
"Clean" from server-owned serials. The nine-clause condition :4437-4507 keeps its clause count and moves its inputs: GetLinkVersion -> record.Serial vs twin->GetSyncedShaderCsoSerial() (the stamp that already exists); GetImageUnitVersion -> record.Serial + BindingsSerial (a glUniform1i on an image uniform moves m_imageUnitVersion, a NewShaderBindings shutter input, so the bindings record re-fires); ComputeShaderStorageBlockBindingSignature -> record.Signature; GetLinkStatus/GetSpirvStatus -> Desc.SpirvStatus plus a new explicit Desc.LinkStatus byte (today "linked" is only implied by the create existing, which is not the same statement); ImageUnitFormatsStillMatch and the patch clauses are S3's / value rows.
Memos. BindCurrentTextures' key (:5274-5283) becomes {handle.Slot, handle.Gen, record.Serial, BindingsSerial}; the sampler-pass memo's backendStateVersion (:5522) becomes BindingsSerial; sampledTargetForUnit (:4845-4857) reads the sampler-unit tail plus the archive's uniform types.
The stash (:4097-4098,:4509-4510,:5332-5335,:5678-5695) holds {MGPipeHandle, BackendProgramObjectImpl*} and consumers compare against MGPipeApplier().DrawProgram instead of GetProgramForDraw().get().
GetProgramObject / ValidateProgramName keep their P9 row: both call sites (:6151, :10020) are GL-thread entry points, not run-ahead ops (7.2).
After this the family's only remaining readers are GetProgramForDraw:92 and GetProgramForDispatch:100, which flip to FATAL under run-ahead (P5e-3) - the strict lane's expected red for this family becomes a gate.

5. Monolith / G1

The pull build compiles none of it: every new site sits under MOBILEGL_PIPE_PUSH, and the registry alias already drops the kind parameter there (Managers.h:626-640), so mangled names stay pre-P2. The record, the applier fields and the emitter method are push-only. G1 byte-identity holds by construction.
Push + Transport=monolith keeps today's behaviour: the run-ahead arm is selected by a transport + caps predicate (ProgramRunAheadArm() beside ProgramSubsystemEnabled()), false under monolith and false for DirectVulkan (P5e-4). Under monolith SyncCurrentProgram keeps the frontend overload verbatim, and with it MapUBO, GetBackendProgramId and ShaderStorageBlockBinding.
Two overloads, not an #if inside one body - the frontend one should be visibly the monolith-glue half, as GetOrCreate(const StatePtr&) is (SlotTables.h:236-244).
G2/G14: one new PipeCalls.def row, no new dirty bit, so gen_pipe_dirty_surface needs only the new emitter's shutter row.

6. Red-once

The bindings record is consumed. Empty the applier's block-binding tail and run UniformInitializerScenario / Glsl420DeclarationScenario: a named UBO lands on the wrong point -> wrong pixels + RefusedObjectCalls. Unit: a ProgramEmitTest case beside MG_Test/Pipe/ProgramEmitTest.cpp:251 ("a glUniformBlockBinding after the link travels on its own record").
The archive is server-owned. Run the run-ahead arm with the blob refs left at Size 0 and the companion pointers removed: the existing trip wire "the record declares no blobs and carries no artefacts" (PipeApply.cpp:2858-2871) fires Fatal{ProtocolCorruption}.
No frontend probe survives. Delete the five scopes of 4.1 without re-keying: MGPipeRefuseAllocatorFromApplyThread (MG_Impl/Pipe/SlotAllocator.cpp:22-38) aborts Fatal{RoleViolation,"MGPipeSlots"} on the first integration-split draw.
GetProgramForDraw is never pulled. integration-split-strict (MOBILEGL_IPC_STRICT_ERRORS=1, ConfigLoader.cpp:382) with the row still BARRIER_PULLED: StrictBarrierPullFatal (MG_Backend/MGPipe/PipeInputs.cpp:60-66) names GetProgramForDraw@draw_vbo. Green after the re-key = P5e-1 for this family.
Relink / identity under run-ahead: RelinkStageSetScenario, PostLinkAttachScenario, ProgramPipelineScenario, AsyncCompileScenario with the client a present ahead; CsoContentAddressingScenario + HandleRecycleScenario for the {slot,gen} ABA.
MapUBO refusal: force bit 12 off under run-ahead and assert G-C's Fatal{UnmigratedVerb,"set_global_constants"} rather than a torn upload.

7. Risks and what I could not settle

Archive cost per link. MC + shader packs link hundreds of programs, some mid-frame. EncodeProgramArtifacts over a full LinkArtifacts (MG_State/GLState/ProgramState/ProgramArtifacts.h:160-342: several String maps, a std::set<String>, seven index vectors) runs only in the verify build today. Needs a measurement before the package is sized. The cheap alternative - the client publishes an immutable SharedPtr<const LinkArtifacts> per link and the record pins it - keeps inproc fast but makes inproc a different code path from a real split, which is against P5e's point. Integrator ruling.
A FAILED relink of a bound program keeps the previous executable running, and the emitter's re-issue rule (ProgramEmit.h:220-226, keyed on GetLinkVersion) fires anyway because BumpLinkObservableVersions runs in Link()'s prologue (ProgramObject.cpp:348-356). Whether the applier keeps the PREVIOUS record live or holds a dead-but-bound one is unsettled. It must NOT be modelled as an object_death - that would collide with S7's "the twin dies at object_death".
Composite programs. GetProgramForDraw flattens a bound pipeline into a client-built composite (MG_State/GLState/Core.cpp:609-628, MG_Impl/Pipe/CompositeResolver.h); the flattening stays on the GL thread at emit and the band handle is fine. What is unsettled is the uniform mirror (Core.cpp:590-606): it rewrites the composite's block bindings every draw, so set_program_bindings may fire per draw for a pipeline workload unless the equality bail-out at ProgramObject.h:1018-1022 absorbs it. Unmeasured.
Sampler-unit tail size. uniformSamplerOrImageUnitIndex is indexed by LOCATION and maxUniformLocation can be in the thousands. The sparse encoding assumes few sampler locations - true for every program CacheResourceLocations walks (Managers.cpp:13040-13077, which skips image uniforms outright) - but a large sampler array is the counter-example. Needs a declared bound and a counted refusal.
Boundary with S5. :5463 (GetUniformBlockBinding) is mine, :5464 onward (the binding point) is S5's, and neither lands alone: set_shader_buffers and set_program_bindings belong to ONE package or the UBO loop keeps a live read either way. Same split at :5504-5506 (the gate is program state, the body is binding points).
Codec completeness. GetUniformType / GetMaxUniformLocation on the alias path (:4849-4852) are covered by G-A only if the archive's uniformIndexInTProgram and type tables survive the codec. ProgramArtifactsCodec.cpp:242 already carries a libc++-branch caveat about a member the codec skips; that member must be named before the design may claim "every reflection question is answered from the archive". Unverified at this head.
